Made after the uncertainty resolves, allowing you to take corrective action (e.g., adjusting production levels). 2. Risk Measures and Quantiles shapiro a lectures on stochastic programming cracked
Corrective actions or "recourse" decisions are made after the random variables reveal themselves. shapiro a lectures on stochastic programming cracked
SAA replaces the true probability distribution with a historical or simulated random sample of size
The average loss in the worst
If the sub-problems show that the master problem underestimated the future costs, mathematical constraints ("cuts") are sent back to the master problem, forcing it to adjust. This loops until the solution converges. Progressive Hedging
